Java Architecture for XML Binding (JAXB) is a Java API that allows Java developers to map Java classes to XML representations.

jaxb-api-2.2.12.jar is the JAR file for the JAXB API 2.2 specification. You can download and use it directly without any building process as shown in the last tutorial.

If you want to rebuild the JAR file, you can download the source code at JAXB API Maven Website.

/**
 * Maps an enum constant in {@link Enum} type to XML representation.  
 * 
 * <p> <b>Usage</b> </p>
 *
 * <p> The <tt>@XmlEnumValue</tt> annotation can be used with the
 *     following program elements:  
 * <ul> 
 *   <li>enum constant</li>
 * </ul>
 *
 * <p>See "Package Specification" in javax.xml.bind.package javadoc for
 * additional common information.</p>
 *
 * <p>This annotation, together with {@link XmlEnum} provides a
 * mapping of enum type to XML representation.
 *
 * <p>An enum type is mapped to a schema simple type with enumeration
 * facets. The schema type is derived from the Java type specified in
 * <tt>@XmlEnum.value()</tt>. Each enum constant <tt>@XmlEnumValue</tt>
 * must have a valid lexical representation for the type
 * <tt>@XmlEnum.value()</tt> 
 *
 * <p> In the absence of this annotation, {@link Enum#name()} is used
 * as the XML representation.
 *
 * <p> <b>Example 1: </b>Map enum constant name -&gt; enumeration facet</p>
 * <pre>
 *     //Example: Code fragment
 *     &#64;XmlEnum(String.class)
 *     public enum Card { CLUBS, DIAMONDS, HEARTS, SPADES }
 *
 *     &lt;!-- Example: XML Schema fragment --&gt;
 *     &lt;xs:simpleType name="Card"&gt;
 *       &lt;xs:restriction base="xs:string"/&gt;
 *         &lt;xs:enumeration value="CLUBS"/&gt;
 *         &lt;xs:enumeration value="DIAMONDS"/&gt;
 *         &lt;xs:enumeration value="HEARTS"/&gt;
 *         &lt;xs:enumeration value="SPADES"/&gt;
 *     &lt;/xs:simpleType&gt;
 * </pre>
 *
 * <p><b>Example 2: </b>Map enum constant name(value) -&gt; enumeration facet </p>
 * <pre>
 *     //Example: code fragment
 *     &#64;XmlType
 *     &#64;XmlEnum(Integer.class)
 *     public enum Coin { 
 *         &#64;XmlEnumValue("1") PENNY(1),
 *         &#64;XmlEnumValue("5") NICKEL(5),
 *         &#64;XmlEnumValue("10") DIME(10),
 *         &#64;XmlEnumValue("25") QUARTER(25) }
 *
 *     &lt;!-- Example: XML Schema fragment --&gt;
 *     &lt;xs:simpleType name="Coin"&gt;
 *       &lt;xs:restriction base="xs:int"&gt;
 *         &lt;xs:enumeration value="1"/&gt;
 *         &lt;xs:enumeration value="5"/&gt;
 *         &lt;xs:enumeration value="10"/&gt;
 *         &lt;xs:enumeration value="25"/&gt;
 *       &lt;/xs:restriction&gt;
 *     &lt;/xs:simpleType&gt;
 * </pre>
 *
 * <p><b>Example 3: </b>Map enum constant name -&gt; enumeration facet </p>
 * 
 * <pre>
 *     //Code fragment
 *     &#64;XmlType
 *     &#64;XmlEnum(Integer.class)
 *     public enum Code {
 *         &#64;XmlEnumValue("1") ONE,
 *         &#64;XmlEnumValue("2") TWO;
 *     }
 * 
 *     &lt;!-- Example: XML Schema fragment --&gt;
 *     &lt;xs:simpleType name="Code"&gt;
 *       &lt;xs:restriction base="xs:int"&gt;
 *         &lt;xs:enumeration value="1"/&gt;
 *         &lt;xs:enumeration value="2"/&gt;
 *       &lt;/xs:restriction&gt;
